Occurs when scanning maven based Java web project during IDE startup. We are
using MyFaces + PrimeFaces JSF technology.
IDE stacktrace:

### Language / Project Type / NetBeans Component
_No response_
### How to reproduce
Occurs each IDE startup. I'm now testing NB 23 RC2.
### Did this work correctly in an earlier version?
Apache NetBeans 22
### Operating System
Windows 10 version 10.0 running on amd64; UTF-8; cs_CZ (nb)
### JDK
21.0.3; Java HotSpot(TM) 64-Bit Server VM 21.0.3+7-LTS-152
### Apache NetBeans packaging
Apache NetBeans binary zip
### Anything else
It seems that it is possible to normally work in NetBeans IDE even after
that NPE.
### Are you willing to submit a pull request?
No
